Electronic Ignition for xs650

I would say the Tytronic is two separate systems on one plate, one pickup coil for each coil.
One would surmise that it could be used with a dual output coil and just wire one pickup in, but you would then need a rotor with two magnets 180deg apart.
Still waiting the results with anticipation.
 
Would be interesting to see if the two outputs could be joined to fire a dual tower coil IE TCI coil... Suspect this would work. A diode on each output might be cheap insurance.

Yep, zackly. That's my plan Gary. I'm in this game, win or lose. I am going to do the same with two sets of points and the MP08 Honda dual output coil with resistor. I was going to do this to get the bike running and then remove the resistor, trade the points for a Pamco. Change of game plan now. I still have the rear fender to fab, then wiring, finish welding, paint and whatnot. Hopefully I'll be testing the Tytronic about March.

I think this is a simple system with a fixed 30% dwell set by the two magnets on the rotor? Probably fine for our 7,000 RPM redline. Probably still fine with both triggers firing one coil?
But I know very little 'bout electronics.
Another possibility would be to add magnets to the rotor to fire a dual tower coil with one trigger like Rasputin suggests.
Was also wondering if these are just generic small engine electronic ignition triggers attached to a motorcycle specific plate with matching rotor.
 
What I'm not seeing is individual timing adjustment for each cylinder, but maybe it has it. Looks like you may have to rely on the accuracy of the trigger mounting locations, and the rotor magnet, to fire each cylinder at the correct time.
 
There's a keyway cut into the rotor, that's a good thing. Those adjustment slots look extra wide, but the adjustment screws must only clamp on one side, not really a slot.
 
The directions for the similar "Charlies Place" ignition warns against using a dynamic timing light. They say that breaking the ground connection at the plate when running, with the plate loosened, will damage the pickups. So, maybe a separate temporary ground connection while zeroing in with a timing light?

in the video of the guy seting the timing, he mentions adjusting one pickup to adjust the timing of the second cylinder, and I don't see any adjustment "visable"

if you're talking about the new ignition having two outputs to fire two coils... electronically i don't think just connecting them directly together would be a problem but a potential problem arises if the two cycles interfere with each other the way it's set up, for example if one side needs the coil to be charging while the other side prevents it. that problem would be there even with diodes. also remember dioes will have about a 0.7 volt drop across it
 
If this uses two coils, that can have an advantage.
When using high dollar iridium plugs they fire best with a certain polarity. I don't recall which for sure, I think it's a negative polarity. As I recall when wired with the wrong polarity they need more voltage to spark.
Well anyway with to coils you can set both plugs to fire with the proper polarity.
As a matter of fact I have been thinking of getting two 5 ohm coils and wiring them in parallel to get the 2,5 ohms the Pamco needs.
Then I could wire them both to have the proper polarity.

I recived the three kits from Tytronics today and they will be shipped to those that wanted them tomarrow morning … first class USPS, should be 3 days until we are trying these out, I have noticed a few things we where all wondering, there is some slots in the sensor 2 for fine tuning of the second coil, (they even came with an allen wrech):laughing: good thing right. anyhow they also come with instructions in chinlesh, but it seems prety basic istall, I also got 100 viton orings 4mm id 1mm cross section 6 mm OD, and ill ship some to anyone who needs them, unrelated to the ignition but can anyone guess where they go?

On the "O" rings...for Idle mixture adjustment screws?
 
huh? no I don't know of a o ring on the float valve, other than the copper washer under the float valve where it screws into the carb body
